This could be interpreted as: "give the use_parent_info param to more

because multiple values of include_parents will confuse the reader and
hence would be difficult to maintain.

Pl. find attached a patch and the corresponding logfile. Its almost
wake-up time now. So, request you to pl. bear with me if I have made any
minor mistakes. :)
